Guides
In-depth explorations of what VoceVista can show you. Each guide pairs a demonstration video with a written companion: the video shows the technique on screen, and the write-up keeps the durable part, the numbers, the reference tables, and the theory, where you can search it, cite it, and come back to it.
For a quick step-by-step on a specific feature, the video tutorials are the faster route; for the official feature-by-feature reference, see the manual.
Technique & Theory
Using ultra-high-resolution spectral views to discern frequencies in recorded and synthetic sounds, and the mathematical limits of the algorithms underneath.
- Sample outline Reading ultra-high-resolution spectra A guided read of a dense spectral view: separating closely spaced partials, telling a real peak from a sidelobe, and knowing when the detail you see is signal rather than artifact.
- Planned The theoretical limits of spectral resolution How far the analysis can actually go: the time-frequency trade-off, what window length buys and costs you, and where the mathematics, not the software, sets the floor.
- Planned Recorded versus synthetic sounds What a synthesized tone looks like next to a real recording of the same note, and what the differences reveal about both the instrument and the analysis.
- Read now High-resolution audio spectrum analyzer The technical-specifications page: sample rates, frequency reach, and what the engine can resolve. The reference companion to the technique guides above.
Gear Tests
How specific microphones and audio interfaces capture different sounds, measured and shown on the spectrogram rather than argued from a spec sheet.
- Planned Microphone test: capturing different sounds The same set of sounds, voice, sustained tones, broadband transients, recorded through a range of microphones, with the spectrograms placed side by side.
- Planned Audio interface comparison What changes, and what does not, when the interface in front of the microphone changes: noise floor, high-frequency reach, and behaviour at high sample rates.
- Read now Microphone recommendations Five tiers from a pocket USB mic to reference-grade measurement microphones, with the rationale for each. The buying-guide companion to the gear tests.
